Frontend Development Guidelines

This document describes various guidelines to ensure consistency and quality across GitLab's frontend team.

Overview

GitLab is built on top of Ruby on Rails using Haml and also a JavaScript based Frontend with Vue.js. Be wary of the limitations that come with using Hamlit. We also use SCSS and plain JavaScript with modern ECMAScript standards supported through Babel and ES module support through webpack.

Working with our frontend assets requires Node (v8.10.0 or greater) and Yarn (v1.10.0 or greater). You can find information on how to install these on our installation guide.

Browser Support

For our currently-supported browsers, see our requirements.

Use BrowserStack to test with our supported browsers. Login to BrowserStack with the credentials saved in GitLab's shared 1Password account.
